BACKGROUND

In late 2019, a novel coronavirus, subsequently named SARS-CoV-2 (COVID-19), was first reported in Hubei province in China. Since it was first reported, a worldwide pandemic has ensued affecting more than 450,000 individuals as of March 2020. In the midst of the pandemic, epidemiological reports unveiled a disproportionate low rate of severe cases among adult females compared to adult males, 42% and 58%, respectively. Similarly, the rate of severe cases among pre-pubescent children was exceptionally low at 0.6% (See Guan W J, Ni Z Y, Hu Y, Liang W H, Ou C Q, et al. Clinical Characteristics of Coronavirus Disease 2019 in China. N Engl J Med. 2020). An explanation for the skewed prevalence of severe COVID-19 infection in adult males has yet to be elucidated.

In newborns, it has long been recognized that male infants are more susceptible to respiratory distress syndrome (See Torday J S, Nielsen H C, Fend Mde M, Avery M E. Sex differences in fetal lung maturation. Am Rev Respir Dis. 1981; 123(2): 205-208) and less likely to respond to prenatal glucocorticoid therapy to protect against respiratory distress. Respiratory distress is intimately tied to the production of pulmonary surfactant, e.g., pulmonary surfactant proteins have been demonstrated to protect against influenza A (See Hartshorn K L, Crouch E C, White M R, Eggleton P, Tauber A I, Chang D, Sastry K. Evidence for a Protective Role of Pulmonary Surfactant Protein D (SP-D) Against Influenza A Viruses. J Clin Invest. 1994; 94 (1): 311-319). In animal studies, it was demonstrated that a sexual dimorphism in fetal pulmonary surfactant production is influenced by the androgen receptor (AR) (See Nielsen H C. Androgen receptors influence the production of pulmonary surfactant in the testicular feminization mouse fetus. J Clin Invest. 1985; 76(1): 177-181). For example, in rabbits, dihydrotestosterone was shown to inhibit fetal pulmonary surfactant production in both males and females while an anti-androgen, flutamide, was demonstrated to remove the sexual dimorphism in surfactant production.

While severe COVID-19 symptoms are primarily manifested in older adults, the similar sexual dimorphism in the severity of respiratory disease is of interest. In addition, AR expression is low prior to pubertal maturation and may contribute to the low incidence of severe COVID-19 infection in children. The lower rate of severe COVID-19 infection in female patients may be attributed to lower androgen receptor expression.

DETAILED DESCRIPTION

SARS-CoV-2 is part of the coronavirus family of viruses including SARS-CoV-1 and MERS-CoV. Coronavirus predominantly infects type II pneumocytes in the human lung (See Shieh WJ, Hsiao CH, Paddock CD, Guarner J, Goldsmith CS, et al. Immunohistochemical, in situ hybridization, and ultrastructural localization of SARS-associated coronavirus in lung of a fatal case of severe acute respiratory syndrome in Taiwan. Hum Pathol. 2005; 36(3): 303-309). It has been demonstrated that SARS-CoV-2 cell entry depends on priming of a viral spike surface protein by transmembrane protease serine 2 (TMPRSS2) present in the host. In type II pneumocytes, TMPRSS2 expression is associated with an increase in androgen receptor (AR) expression (See Mikkonen L, Pihlajamaa P, Sahu B, Zhang F P, Janne O A. Androgen Receptor and Androgen-Dependent Gene Expression in Lung. Mol Cell Endocrinol. 2010; 317 (1-2): 14-24), specifically connecting AR expression to SARSCoV-2, due to AR-regulated TMPRSS2 gene promoter (See Lin B, Ferguson C, White J T, Wang S, Vessella R, True L D, et al. Prostate-localized and androgen-regulated expression of the membrane-bound serine protease TMPRSS2. Cancer Res 1999; 59: 4180-4). Moreover, angiotensin converting enzyme 2 (ACE2) has been recognized as the attachment molecule to the viral spike surface protein, thus termed the “receptor of SARS-CoV-2” (See Y. Qiu, Y.-B. Zhao, Q. Wang, J.-Y. Li, Z.-J. Zhou, C.-H. Liao, X.-Y. Ge,Predicting the angiotensin converting enzyme 2 (ACE2) utilizing capability as the receptor of SARS-CoV-2, Microbes and Infection, https://doi. org/10.1016/j.micinf.2020.03.003).

As used herein, the terms “prevent” or “prevention” and other derivatives of the words, when used in reference to viral respiratory infection, e.g., viral respiratory infection, refer to a reduced likelihood of viral respiratory infection in an individual receiving a given treatment relative to that of a similar individual at risk for viral respiratory infection but not receiving that treatment. As such, the terms “prevent” and “prevention” encompass a treatment that results in a lesser degree of viral respiratory infection, e.g., viral respiratory infection, than would be otherwise expected for a given individual. Efficacy for prevention of viral respiratory infection, e.g., viral respiratory infection, can be established through controlled studies, e.g., in which a subject is administered a treatment (e.g., an inhaled treatment) and another subject is administered a placebo. Under these circumstances, if the subject treated with the inhaled treatment undergoes less severe viral respiratory infection symptoms over time relative to the subject receiving the placebo, e.g., at least 5% less, at least 10% less, at least 15% less, at least 20% less, at least 25% less, at least 30% less, at least 35% less, at least 40% less, at least 45% less, at least 50% less or beyond, the treatment is effective for the prevention of viral respiratory infection

As used herein, the terms “treat,” “treatment,” or “treating” refer to therapeutic treatments, wherein the object is to reverse, alleviate, ameliorate, inhibit, slow down or stop the progression or severity of a disease or condition, e.g., viral respiratory infection. The term “treating” includes reducing or alleviating at least one adverse effect or symptom of a disease or condition, e.g., viral respiratory infection. Treatment is generally “effective” if one or more symptoms are reduced. Alternatively, treatment is “effective” if the progression of a disease is reduced or halted. That is, “treatment” includes not just the improvement of symptoms, but also a cessation of, or at least slowing of, progress or worsening of symptoms compared to what would be expected in the absence of treatment. Beneficial or desired clinical results include, but are not limited to, alleviation of one or more symptom(s), diminishment of extent of disease, stabilized (i.e., not worsening) state of disease, delay or slowing of disease progression, amelioration or palliation of the disease state, remission (whether partial or total), and/or decreased mortality. For example, treatment is considered effective if: 1) the risk or propensity of a person having a viral respiratory infection being hospitalized, being admitted to an intensive care unit (ICU), or dying as a result is reduced; 2) the rate at which a person having a viral respiratory infection recovers or stabilizes is increased; 3) the rate at which a person having a viral respiratory infection is discharged from the hospital is increased; 4) the ability for a person having a viral respiratory infection to recover or stabilize is improved; 5) the ability to diagnose a person as having a viral respiratory infection is improved; 6) the time to diagnose a person having a viral respiratory infection is reduced; 7) the ability to prevent a person from being infected with a viral respiratory infection is improved; 8) the ability to predict viral respiratory disease severity (e.g., is a ventilator or respirator will be needed for treatment) is increased. The term “treatment” of a disease also includes providing relief from the symptoms or side-effects of the disease (including palliative treatment). Treatment can involve administering a therapeutically effective amount of any one or combination of the compositions disclosed herein.

As used herein the term “comprising” or “comprises” is used in reference to compositions, methods, etc. refers to component(s) or method steps that are present in the method or composition, yet allows for the composition, method, etc. to also include unspecified elements.

The term “consisting of” refers to compositions, methods, and respective components thereof as described herein, which are exclusive of any element not recited in that description of the embodiment.

As used herein the term “consisting essentially of” refers to those elements required for a given embodiment. The term permits the presence of elements that do not materially affect the basic and novel or functional characteristic(s) of that embodiment.

As used herein the term “viral respiratory infection” refers to all forms of human lung disease stemming from a viral infection including coronavirus, influenza, influenza A, influenza B, SARS-CoV-1, SARS-CoV-2, MERS-CoV and rhinoviruses. The term permits the presence of elements that do not materially affect the basic and novel or functional characteristic(s) of that embodiment.

The singular terms “a,” “an,” and “the” include plural referents unless context clearly indicates otherwise. Similarly, the word “or” is intended to include “and” unless the context clearly indicates otherwise. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of this disclosure, suitable methods and materials are described below. The abbreviation, “e.g.” is derived from the Latin exempli gratia, and is used herein to indicate a non-limiting example. Thus, the abbreviation “e.g.” is synonymous with the term “for example.”

Various aspects of the technology describe detecting androgen sensitivity in a subject by measuring polymorphisms in the androgen receptor gene. Androgen Receptor (AR) genetic variation refers to DNA genetic variations, expression of AR in specific tissue (RNA), including methylation analysis of AR (i.e., in the case of X-chromosome inactivation). Specific details for detecting polymorphisms in the androgen receptor can be found in literature, e.g., See Androgens and Androgen Receptor: Mechanisms, Functions, and Clini Applications. United States, Springer US, 2012, which is incorporated here in its entirety. Polymorphisms in the androgen receptor can be used to infer a subject has androgen sensitivity.

Applicants disclose herein systems, methods, and kits for treating, preventing, and diagnosing viral respiratory infection by first measuring polymorphisms in the androgen receptor gene. The method includes the use of compositions including any one or combination of the following: androgen receptor antagonists, androgen synthesis inhibitors, agents that counter the effect of androgens such as sex hormone-binding globulin (SHBG) stimulators, antigonadotropins, mineralocorticoids and glucocorticoids (anticorticotropins) suppressing androgen production in the adrenal gland, insulin sensitizing medications (e.g., metformin), and vaccines or immunogens against androstenedione that reduce the level of testosterone as a treatment for viral respiratory disease. The use of the composition can involve administering the composition to a subject or a patient. For instance, the composition can be administered topically, nasally, orally, by injection, or be applied topically to the lung, i.e. inhaled. Compositions applied to a subject alter androgen receptor function and subsequently down stream genes under regulatory control of the androgen receptor. Such genes include but are not limited to, angiotensin converting enzyme 2 (ACE2), furin, and transmembrane protease serine 2 (TMPRSS2). Blocking the production of certain proteins in the lung may be beneficial to altering viral entry into cells or bolstering host immunity. For example, TMPRSS2 priming of a viral spike surface protein is required for SARS-CoV-2 cell entry; TMPRSS2 expression is under control of the androgen receptor. As such, blocking the expression of the androgen receptor or altering AR activity (e.g., with and AR antagonist) would decrease the amount of TMPRSS2 expression and lead to reduced viral entry. Other embodiments are described below.

In certain embodiments, a genetic variation in the androgen receptor (AR) gene can be used to predict mortality from viral respiratory infection. In another embodiment, a genetic variation in the androgen receptor (AR) gene can be used to predict viral respiratory infection symptom severity. In yet another embodiment, a genetic variation in the androgen receptor (AR) gene can be used to predict if a patient with viral respiratory infection will need a ventilator or a respirator.

In certain embodiments of present invention, a cut off value for the number of CAG repeats the first exon of AR gene can be used to define a person with androgen sensitivity. In one embodiment, the cut-off value for the number of CAG repeats the first exon of AR gene is 24.

Following 15 days of treatment, 84% of the subjects in the cyproterone acetate survived while 64% of the control group survived.

Example 8: A double-blinded placebo controlled study was conducted on 340 male patients with average age of 39.2 years old.

Patients were diagnosed with SARS-CoV-2 infection but were showing relatively mild symptoms. Patients were divided into one of two arms. The treatment arm received a subcutaneous injection of degarelix (120 mg) at the start of the trial. Each group received tablets of bicalutamide (50 mg) or a placebo and were instructed to take 1 tablet daily. Patients were instructed to go home but return to the hospital if symptoms became worse. Efficacy parameters were defined as 1.) COVID-19 Diagnosis: COVID-19 positive diagnosis is defined as subject exhibiting symptoms of acute respiratory infection, defined as one or more of the following cough, fever (>37.5° C./99.5° F.), shortness of breath, sore throat, and a positive SARS-CoV-2 rtPCR test 2.) COVID-19 Hospitalization defined as confirmed hospitalization due to COVID-19, and 3.) Symptoms Severity of COVID-19 defined as symptoms severity of COVID-19 using Brescia-COVID Respiratory Severity Scale (BCRSS).

All subjects were tested and found to be positive for SARS-CoV-2 infection. All subjects were monitored for one month after the initiation of the therapy. 2 of 180 subjects in the bicalutamide plus degarelix arm were admitted to the hospital after their first visit. The average BCRSS score for the 2 admitted patients was 2.5. 31 of 160 in the placebo group were admitted to the hospital with an average BCRSS score of 6.2.

Example 9: A controlled study was conducted on 140 male patients with average age of 42.6 years old. Patients were diagnosed with sars-CoV-2 infection but were showing relatively mild symptoms. Patients were divided into one of two arms. The treatment arm received a subcutaneous injection of degarelix (120 mg) at the start of the trial, the control arm received standard care. Patients were instructed to go home but return to the hospital if symptoms became worse. Efficacy parameters were defined as 1.) COVID-19 Diagnosis: COVID-19 positive diagnosis is defined as subject exhibiting symptoms of acute respiratory infection, defined as one or more of the following cough, fever (>37.5° c./99.5° f.), shortness of breath, sore throat, and a positive SARS-CoV-2 rtPRCR test 2.) COVID-19 Hospitalization defined as confirmed hospitalization due to COVID-19, and 3.) symptoms severity of COVID-19 defined as symptoms severity of COVID-19 using Brescia-COVID Respiratory severity Scale (BCRSS).

All subjects were tested and found to be positive for SARS-CoV-2 infection. All subjects were monitored for one month after the initiation of the therapy. 3 of 80 subjects in the degarelix arm were admitted to the hospital after their first visit. The average BCRSS score for the 2 admitted patients was 1.3. 12 of 60 subjects in the standard care group were admitted to the hospital with an average BCRSS score of 4.6.

Example 10: A double-blinded placebo controlled study was conducted on 25 male patients admitted to the hospital for complication resulting from flu with average age of 68.4 years old. Patients were diagnosed with influenza a infection. patients were divided into one of two arms. The treatment arm received a subcutaneous injection of degarelix (120 mg) at the start of the trial. Each group received 1 tablet of bicalutamide (50 mg) or a placebo daily. Patient progress was monitored by primary care physician. Efficacy parameters were defined as 1.) time to alleviation of fever 2.) mortality and length of hospital stay 3.) change in virus titer 48 hours after hospital admission.

All subjects were tested and found to be positive for Influenza A infection. 15 subjects were in the treatment group and 9 were in the placebo arm. Overall, the time to alleviation of fever was lower in the treated group compared with the control group [mean difference (MD), −7.17 hours; 95% confidence interval (CI) −11.00 to −3.34]. Mortality, length of hospital stay, change in virus titer 48 hours after admission, and the incidence of adverse events in these patients were not significantly different between the two groups.

Example 11: A double-blinded placebo controlled study was conducted on 36 male health care workers working at two hospital emergency room departments.

At baseline, all subjects were tested and found to be negative for SARS-CoV-2 infection. 18 subjects applied twice daily a topical ocular solution containing a low dosage finasteride. The reminder 18 subjects were given a placebo vehicle ocular solution. At day 28 all subjects were tested again for SARS-CoV-2 infection. Among the subjects that were administered finasteride, 1 subject tested positive for SARS-CoV-2. Among the subjects administered the placebo, 6 subjects tested positive for SARS-CoV-2.
